technical field

The present invention relates to the field of communications, and more particularly, to a power determination method, user equipment and base station.

Background technique

In the LTE-A system, in order to meet the peak data rate requirements of the International Telecommunication Union for the fourth-generation communication technology, carrier aggregation (Carrier Aggregation, referred to as "CA") technology, also known as spectrum aggregation (Spectrum Aggregation) technology or bandwidth expansion is introduced. (BandwidthExtension) technology. In carrier aggregation, the spectrums of two or more component carriers are aggregated together to obtain a wider transmission bandwidth. The spectrum of each component carrier can be adjacent continuous spectrum or within the same frequency band. Non-adjacent spectrum is even discontinuous spectrum in different frequency bands; LTE Rel-8/9 user equipment (User Equipment, "UE") can only access one of the component carriers for data transmission and reception, while LTE-A user equipment Capability and service requirements can simultaneously access multiple component carriers for data transmission and reception.

In order to support dynamic scheduling and downlink Multiple Input Multiple Output (Multiple Input Multiple Output, referred to as

"MIMO") transmission and hybrid automatic retransmission and other technologies, the terminal needs to feed back a variety of Uplink Control Information ("UCI" for short) includes Channel State Information ("CSI" for short), Hybrid Automatic Repeat request ("HARQ" for short) information, and scheduling request ("HARQ" for short). SchedulingRequest, referred to as "SR"), etc., in which the mixed automatic retransmission request information can also be simply referred to as Acknowledgment (referred to as "ACK")/Negative Acknowledgement (referred to as "NACK"), or mixed automatic retransmission request The information may also be referred to as Hybrid Automatic Repeat Request Acknowledgement HARQ-ACK.

For example, multiple PUCCHs will be transmitted at the same time, or multiple PUSCHs with UCI will be transmitted. In this way, all pending transmissions will occur. The sum of the transmit powers of the uplink channel and/or the Sounding Reference Signal (SRS for short) may exceed the maximum transmit power of the user equipment, so that the information transmission of the user equipment cannot be performed normally.

FIG. 1 shows a schematic flowchart of a power determination method 100 . Wherein, the method 100 may be executed by a user equipment. As shown in Figure 1, the method 100 includes:

S110, determining the initial transmit power of each transmission object in the transmission object set, wherein the transmission object set includes all uplink channels and/or SRSs to be transmitted;

S120, when the sum of the initial transmission powers of each transmission object in the transmission object set is greater than the maximum transmission power, perform a power reduction operation based on the priority ordering of the corresponding information of the transmission objects to obtain each transmission object in the transmission object set The available transmission power of the transmission object, wherein the sum of the available transmission power of each transmission object in the transmission object set is not greater than the maximum transmission power;

S130: Send each transmission object in the transmission object set according to the available transmit power corresponding to each transmission object in the transmission object set.

Specifically, when it is necessary to transmit uplink channels and/or SRSs corresponding to multiple carriers at the same time (ie, a set of transmission objects), the user equipment may first calculate the initial transmit power of each transmission object in the set of transmission objects, and then calculate the initial transmit power of each transmission object in the set of transmission objects. After the initial transmit power of a transmission object, the user equipment can compare the sum of the initial transmit power of each transmission object with the maximum transmit power, and when the sum of the initial transmit power of each transmission object is less than or equal to the maximum transmit power, Each transmission object in the transmission object set can be directly sent. When the sum of the initial transmission power of each transmission object is greater than the maximum transmission power, a power reduction operation needs to be performed. Specifically, the priority of the corresponding information of the transmission object can be firstly performed. Sorting, and the corresponding information of each transmission object in the transmission object set, determine the priority of each transmission object, and then perform a power reduction operation according to the priority of each transmission object, so as to obtain each transmission object in the transmission object set. The available transmit power of a transmission object, wherein the sum of the available transmit power of each transmission object in the transmission object set is not greater than the maximum transmit power, after obtaining the available transmit power of each transmission object in the transmission object set , the user equipment may send each transmission object in the transmission object set according to the available transmit power corresponding to each transmission object in the transmission object set.

It should be noted that, in the actual implementation process, due to the device and other reasons, the sum of the available transmit power of each transmission object in the transmission object set may exceed the maximum transmit power of the user equipment within a small period of time, but in the After the device is stabilized, the sum of the available transmit power of each transmission object in the set of transmission objects is not greater than the maximum transmit power.

In this embodiment of the present invention, the initial transmit power of the transmission object is the transmit power of the transmission object calculated by the user equipment according to the relevant power control rule before performing the power reduction operation. If the sum does not exceed the maximum transmit power of the user equipment, the user equipment needs to transmit the corresponding transmission object according to the initial transmit power. If the sum of the initial transmit power of the transmission objects to be transmitted of the user equipment exceeds the maximum transmit power of the user equipment, then The user equipment needs to perform a power reduction operation to obtain the available transmit power of each transmission object.

It should be understood that, in this embodiment of the present invention, the available transmit power for a certain transmission object may be equal to its initial transmit power, or may not be equal to its initial transmit power, for example, for a transmission object with a higher priority, its available transmit power The transmit power may be equal to the initial transmit power, while for the lower priority transmission object, the available transmit power is less than the initial transmit power.

In this embodiment of the present invention, the uplink channels and/or SRSs corresponding to multiple carriers that need to be transmitted at the same time may be the uplink channels and/or SRSs corresponding to the multiple carriers that need to be transmitted in the same subframe; Although the uplink channels and/or SRSs corresponding to the two carriers need to be transmitted at the same time in terms of time, the subframe numbers sent by different uplink channels and/or SRSs may be inconsistent. Therefore, the objects that need to be transmitted at the same time can also be understood as Objects that need to be transmitted at a certain point in time or period of time.

In this embodiment of the present invention, the transmission object set includes all uplink channels and/or SRSs to be transmitted means: in the case that only uplink channels need to be transmitted, the transmission object set includes all uplink channels to be transmitted; When the SRS needs to be transmitted, the transmission object set includes all the SRSs to be transmitted; when the uplink channel and the SRS need to be transmitted at the same time, the transmission object set includes all the uplink channels and all the SRSs to be transmitted.

It should be understood that, in this embodiment of the present invention, the priority ordering of the information corresponding to the transmission objects may be preset, may be dynamically set by the user equipment according to high-level configuration, or may be obtained by the user equipment through other channels. The embodiment does not make any limitation on this.

In this embodiment of the present invention, the priority ordering of the information corresponding to the transmission objects may include:

At least one of the priority ordering of the types of the transmission objects, the priority ordering of the UCI carried by the transmission objects, and the priority ordering of the carriers corresponding to the transmission objects.

In the embodiment of the present invention, performing a power reduction operation based on the priority ordering of the corresponding information of the transmission objects may include:

Determine the priority of each transmission object in the transmission object set according to the priority ordering of the corresponding information of the transmission object and the corresponding information of each transmission object in the transmission object set;

In all embodiments of the present invention, the corresponding information of the transmission object may refer to the type corresponding to the transmission object. For example, the corresponding type of a transmission object may be a PRACH channel, a PUCCH channel, and a PUSCH channel (specifically, a PUSCH channel that carries UCI and a channel that does not carry UCI). The PUSCH channel of UCI), or the SRS channel; the corresponding information of the transmission object can also refer to the information carried by the transmission object, for example, the corresponding information of a transmission object can be uplink control information UCI, PUSCH data or SRS; the corresponding information of the transmission object can also be Refers to the information of the carrier corresponding to the transmission object, etc.

A power reduction operation is performed according to the priority of each transport object in the set of transport objects.

In this embodiment of the present invention, the user equipment may determine the priority of each transmission object in the transmission object set only according to the priority ordering of the types of transmission objects and the type of each transmission object in the transmission object set; or The priority of each transfer object in the transfer object set can be determined only according to the priority ordering of the UCI carried by the transfer object and the UCI carried by each transfer object in the transfer object set; of course, the priority of each transfer object in the transfer object set can also be determined; The priority ordering of the carriers and the carrier corresponding to each transmission object in the transmission object set determine the priority of each transmission object.

In this embodiment of the present invention, the user equipment may also first determine the priority of each transmission object according to one of the priority ordering of the type of the transmission object, the priority ordering of the UCI carried by the transmission object, and the priority of the carrier corresponding to the transmission object In the case of the same priority, the priority is determined according to the other two or one of the priority ordering of the type of the transmission object, the priority ordering of the UCI carried by the transmission object, and the priority ordering of the carrier corresponding to the transmission object. The priority of the same transfer object.

For example, the priority of each transmission object in the set S of transmission objects can be determined according to the priority ordering of the types of the transmission objects. A plurality of transmission objects with the same priority determined by the priority ordering of the types of the transmission objects constitute a transmission object set S1, and then the priority order corresponding to each transmission in the transmission object set S1 is further determined according to the priority ordering of the UCI carried by the transmission objects. If it is determined according to the priority ordering of the UCI carried by the transmission objects that the priorities of multiple transmission objects in the transmission object set S1 are the same, it is assumed that multiple transmission objects with the same priority in the transmission object set S1 form a set S2, and then The priority of each transmission object in the set S2 is further determined according to the priority ordering of the carriers corresponding to the transmission objects. For multiple transmission object sets S2 with the same priority in the transmission object set S1, if the S2 includes PUCCH1 carrying HARQ-ACK transmission and PUCCH2 carrying HARQ-ACK transmission, the HARQ-ACK transmission on PUCCH1 and PUCCH2 can also be used. For example, the priority of a PUCCH with a large number of HARQ-ACK bits is higher than that of a PUCCH with a small number of HARQ-ACK bits.

For example, the user equipment can determine the priority of each transmission object in the transmission object set according to the priority ordering of the transmission object types and the type of each transmission object in the transmission object set;

When the priority of each transmission object in the set of transmission objects determined according to the type of the transmission object and the priority of each transmission object is the same, according to the priority of the UCI carried by the transmission object, and the UCI carried by each of the transport objects of equal priority, determining the priority of each of the transport objects of equal priority, or

The priority of each transmission object in the transmission objects with equal priorities is determined according to the priority ordering of the carriers corresponding to the transmission objects and the carriers corresponding to each transmission object in the transmission objects with equal priorities.

In this embodiment of the present invention, the types of transmission objects may be divided into PRACH, PUCCH, PUSCH carrying UCI, PUSCH and SRS not carrying UCI, and the priority ordering of the types of transmission objects may include at least one of the following:

When there is PRACH, PRACH has the highest priority;

When PUCCH and PUSCH coexist, the priority of PUCCH is higher than the priority of PUSCH, or the priority of PUCCH is higher than that of PUSCH without UCI and the same as that of PUSCH with UCI;

When a PUSCH carrying uplink control information UCI and a PUSCH not carrying UCI coexist, the priority of carrying UCI is higher than that of PUSCH not carrying UCI;

When PRACH, PUCCH, PUSCH and SRS coexist, SRS has the lowest priority.

Specifically, the priority ordering of the types of the transmission objects may also be: the priority of PRACH is higher than the priority of PUCCH, the priority of PUCCH is higher than the priority of PUSCH carrying UCI, and the priority of PUSCH carrying UCI is higher Regarding the priority of the PUSCH without UCI, the priority of the PUSCH without UCI is higher than the priority of the SRS. Or the priority ordering of the type of the transmission object may also be: the priority of PRACH is higher than the priority of PUCCH, the priority of PUCCH is equal to the priority of PUSCH carrying UCI, the priority of PUSCH carrying UCI is higher than that of PUSCH not carrying UCI The priority of the PUSCH, the priority of the PUSCH without UCI is higher than the priority of the SRS.

In the embodiment of the present invention, if the priority of the PUCCH is the same as the priority of the PUSCH carrying the UCI, more important UCI information can be better protected in some application scenarios. For example, when the UCI carried in the PUSCH carrying the UCI is HARQ-ACK, and the UCI carried in the PUCCH is the channel state information, first set the priority of the PUCCH and the PUSCH carrying the UCI to be the same, and then set the priority of the PUCCH and the PUSCH carrying the UCI to the same priority. The priority of the PUCCH carrying the UCI and the PUSCH carrying the UCI are determined according to the priority of the carried UCI, and it can be determined that the PUSCH carrying the HARQ information has a higher priority, thereby comparing the HARQ information. High protection ensures the transmission performance of this type of important information. This beneficial effect can be obtained in the scenario of dual connectivity, or in the scenario in which UCI can be simultaneously transmitted on multiple uplink carriers, or in the scenario in which multiple PUCCHs are allowed to be simultaneously transmitted on multiple carriers.

In this embodiment of the present invention, the UCI carried by the transmission object may be divided into hybrid automatic repeat request information, scheduling request and channel state information, wherein the priority ordering of the UCI carried by the transmission object may include at least one of the following:

When there is channel state information and a scheduling request, the priority of the channel state information is lower than that of the scheduling request;

When there are hybrid automatic repeat request information and scheduling request, the priority of the hybrid automatic repeat request information is higher than or equal to the priority of the scheduling request.

In this embodiment of the present invention, the priority ordering of the UCI carried by the transmission object may include at least one of the following:

When there is channel state information, and the channel state information includes a channel quality indicator and a precoding matrix, the priority of the channel quality indicator is equal to the priority of the precoding matrix;

When there is channel state information, and the channel state information includes a rank indication, a channel quality indication and a precoding matrix, the priority of the rank indication is the highest.

It should be understood that, in this embodiment of the present invention, the priority of each transmission object is determined according to the UCI carried by the transmission object, and the priority of each transmission object may be determined according to the priority of the UCI with the highest priority carried by each transmission object. Priority, for example, the UCI information carried by PUCCH channel 1 only includes the scheduling request, and the UCI information carried by PUCCH channel 2 only includes the channel quality indicator and the precoding matrix. order, the priority of PUCCH channel 1 is higher than the priority of PUCCH channel 2.

In this embodiment of the present invention, the priority ordering of the carriers corresponding to the transmission objects may include:

Priority ranking based on carrier index number, carrier priority ranking configured by high layer, priority ranking based on carrier duplex mode, priority ranking based on transmission point corresponding to carrier, and carrier-based RRC connection status determination at least one of the priorities.

In this embodiment of the present invention, the index of the carrier may be pre-configured, and the pre-configured index of the carrier may be set according to the importance of the carrier relative to the user equipment. If the order of importance is from high to low, that is, the index of the carrier with high importance is small, the priority rule corresponding to the carrier index is that the order of priority from high to low is the order of increasing carrier index, that is, the carrier index Smaller carriers have higher priority. Of course, it can also be sorted according to the order of importance from low to high, that is, the index of the carrier with high importance is large, then the priority rule corresponding to the carrier index is that the order of priority from high to low can be the order of decreasing carrier index. , that is, a carrier with a smaller carrier index has a lower priority.

In this embodiment of the present invention, the priority order corresponding to the carriers from high to low may be the order configured by the high layer, that is, the priority order may be the order notified by the high layer through semi-static signaling.

In this embodiment of the present invention, a carrier may correspond to a corresponding transmission point, or may correspond to a corresponding base station. For example, carrier 1 comes from a macro base station, and carrier 2 comes from a micro base station. In this case, the carrier priority is the transmission point priority. Or the base station priority. Taking the user equipment aggregated with two uplink carriers as an example, the priority corresponding to the carrier may be that the priority of the carrier corresponding to the macro base station (Macro) is higher than the priority of the carrier corresponding to the micro base station (Pico). This situation is mainly used in the scenario of transmitting radio resource control (Radio Resource Control, "RRC") control information of the user equipment and/or semi-persistent scheduling of SPS services. At this time, the RRC control information and/or semi-persistent Better protection of scheduling (Semi Persistent Scheduling, "SPS" for short) service data.

In this embodiment of the present invention, the priority ordering of the carriers corresponding to the transmission objects may include: the priority ordering determined based on the duplex mode of the carriers, for example, the priority ordering of the carriers whose duplex mode is Frequency Division Duplexing (FDD) The priority is lower than the priority of the carrier whose duplex mode is Time Division Duplexing (TDD).

Specifically, the priority ordering based on the corresponding information of the transmission objects may include at least one of the following:

The priority of the PUCCH transmitted on the carrier whose duplex mode is frequency division duplex is lower than that of the PUCCH transmitted on the carrier whose duplex mode is TDD. At this time, the PUCCH and the The PUCCH transmitted on the TDD duplex mode may be the PUCCH carrying the hybrid automatic repeat request information;

The priority of the PUCCH transmitted on the carrier whose duplex mode is FDD is lower than the priority of the PUSCH carrying UCI transmitted on the carrier whose duplex mode is TDD. The UCI carried in the PUSCH of the UCI includes HARQ information.

In all the embodiments of the present invention, when the priority order of the carrier corresponding to the transmission object is the priority order determined based on the duplex mode of the carrier, it is beneficial to the scenario of the combined application of TDD and FDD. For example, in this scenario, if the PUCCH transmitted on the carrier whose duplex mode is FDD and the PUCCH transmitted on the carrier whose duplex mode is TDD coexist, and the PUCCH and the PUCCH transmitted on the carrier whose duplex mode is FDD When the PUCCHs transmitted on the carrier whose duplex mode is TDD are all PUCCHs that carry HARQ information, usually the PUCCHs that are transmitted on the carrier whose duplex mode is TDD carry HARQ-ACKs of multiple downlink subframes , and the PUCCH transmitted on the carrier whose duplex mode is FDD may only carry the HARQ-ACK of one downlink subframe, then according to the priority order determined based on the carrier duplex mode, on the carrier whose duplex mode is TDD The priority of the transmitted PUCCH is higher than that of the PUCCH transmitted on the carrier whose duplex mode is FDD, thereby ensuring the performance of the PUCCH transmitted on the carrier whose duplex mode is TDD, so that the duplex mode is TDD. Data of multiple downlink subframes on the carrier does not need to be retransmitted, which improves system performance.

In this embodiment of the present invention, the priority ordering of the carriers corresponding to the transmission objects may include: a priority ordering determined based on the RRC connection status of the carriers, for example, the priority ordering of the carriers that support RRC connection may be higher than that of the carriers that do not support RRC connection. The priority, or the priority of the carrier carrying the RRC information may be higher than the priority of the carrier not carrying the RRC information. In this embodiment of the present invention, the user equipment may first determine the priority of the transmission object according to the priority order determined based on the RRC connection situation. For example, if carrier 1 is a carrier that supports RRC connection, and carrier 2 is a carrier that does not support RRC connection, then The priority of carrier 1 is higher than the priority of carrier 2, that is, regardless of the type corresponding to the transmission object corresponding to carrier 1 and carrier 2, or regardless of the UCI carried by the transmission object corresponding to carrier 1 and carrier 2, carrier 1 corresponds to The priority of the transmission object is higher than the priority of the transmission object corresponding to carrier 2. When the priority of the transmission object is determined according to the priority order determined based on the RRC connection situation, if there is still a transmission object with the same priority, the priority of the corresponding type of the transmission object and/or the priority of the UCI carried by the transmission object may be used again. The level further determines the priority of the transfer object.

In this embodiment of the present invention, performing a power reduction operation according to the priority of each transmission object may include:

The power reduction operation is performed according to the priority order of each transmission object in the transmission object set from low to high, and the power reduction operation is performed until the obtained sum of the available transmit power of each transmission object in the transmission object set less than or equal to the maximum transmit power.

In this embodiment of the present invention, the power reduction method according to the priority order of the transmission objects from low to high satisfies that the priority order is n+1 when the available transmit power of the priority order n is not 0 The available transmit power of the transmission object is equal to the requirement of the initial transmit power, where m is the number of transmission objects in the transmission object set, m≥n≥1, and the transmission object whose priority is 1 has the lowest priority.

That is, after determining the priority of each transmission object based on the priority sorting, the transmission power of the transmission object with the lowest priority can be reduced in power first, if the initial transmission power of the transmission object with the lowest priority can meet the reduction requirements , that is, when the initial transmission power with the lowest priority is greater than the difference between the initial transmission power of each transmission object in the transmission object set and the maximum transmission power of the user equipment, only the transmission object with the lowest priority is subjected to power reduction to obtain the priority. The available transmit power of the transmission object with the lowest priority, and the available transmit power of other transmission objects is equal to the initial transmit power; if the initial transmit power of the transmission object with the lowest priority cannot meet the reduction requirement, the transmission object with the lowest priority will be reduced in power first. , obtain that the available transmit power of the transmission object with the lowest priority is 0, and then reduce the power of the transmission object with the second lowest priority, if the initial transmit power of the transmission object with the second lowest priority can meet the reduction requirement, that is, by When the sum of the initial transmit power with the lowest priority and the initial transmit power with the next lowest priority is greater than the difference between the initial transmit power of each transmission object in the set of transmission objects and the maximum transmit power of the user equipment, the transmission object with the next lowest priority Power reduction is performed to obtain the available transmit power with the second lowest priority, and the available transmit power of other transmission objects (other than the transmission object with the second lowest priority and the transmission pair with the lowest priority in the transmission object set) The power is equal to the initial transmit power; if the initial transmit power of the transmission object with the second lowest priority cannot meet the reduction requirement, the power reduction is performed on the transmission object with the third-to-last priority, and so on, until every transmission in the transmission object set The sum of the available transmit power of the object is equal to or equal to the maximum transmit power of the user equipment.

In this embodiment of the present invention, when there are multiple transmission objects under the same priority, equal power reduction may be performed on the multiple transmission objects under the same priority.

In this embodiment of the present invention, the operation of equal power reduction may be to perform equal power reduction in proportion to the objects that need to perform power reduction, that is, the ratio of the initial transmit power to the available transmit power of each transmission object that has undergone power reduction is the same value. The same value of power may also be subtracted from the initial transmit power of the transmission object that needs to be reduced in power.

Assume that the transmission objects of the same priority that need to perform power reduction include transmission objects A, B and C, the initial transmission power corresponding to transmission object A is a, the initial transmission power corresponding to transmission object B is b, and the transmission transmission power of transmission object C is c, the power that needs to be reduced is d. The equal power reduction operation can be directly performed on all transmission objects proportionally, that is, according to the formula

w(a+b+c)=d to obtain the coefficient w, thus, the powers that need to be reduced for the transmission object ABC can be obtained as wa, wb and wc respectively, that is, the available transmit powers are respectively a-wa, b-wb and c-wc. It can also be the power of the same value subtracted from the initial transmit power of the transmission object that needs to be reduced in power, that is, e can be obtained according to formula 3e=d, then the powers of the transmission objects A, B, and C that need to be reduced are d/ 3, that is, the available transmit powers are a-d/3, b-d/3, and c-d/3, respectively.

It should be understood that, in this embodiment of the present invention, power reduction of the transmission object may also be performed in other manners. For example, power reduction may be performed on all transmission objects, for example, according to the formula ma+nb+pc=D, where the numerical relationship between m, n and p may be determined according to the priority of the corresponding transmission object, Therefore, it is possible to wait until the transmit powers of the transmission objects A, B, and C are ma, nb, and pc, respectively.

Of course, in this embodiment of the present invention, power reduction may also be performed in other manners, which is not limited in this embodiment of the present invention.

In order to understand the present invention more clearly, the power determination method of the present invention will be described below with reference to several examples. In the following example, it is assumed that the user equipment aggregates two uplink carriers, that is, carrier 1 and carrier 2. Multiple objects to be transmitted are sent on the same subframe, and the sum of the transmit power of each object to be transmitted is greater than the maximum transmit power of the user equipment. For the convenience of description, the transmission power in the following examples is characterized by a linear value of the transmission power. Of course, it can also be characterized by other values, such as the absolute value of the transmission power or the relative value of the transmission power.

Example 1:

The objects to be transmitted are PUCCH channel 1 that needs to be transmitted on carrier 1 and PUCCH channel 2 that needs to be transmitted on carrier 2. In this example, only the priorities of the channels are compared. If the priorities of the two channels are the same, you can Equal power reduction is performed on the transmit powers of the two PUCCH channels, and the reduction coefficient can be obtained by the following formula:

in is the linear value of the maximum transmit power, is the linear value of the initial transmit power of PUCCH channel 1, is the linear value of the initial transmit power of PUCCH channel 2, so the linear values of the reduced transmit power of PUCCH on carrier 1 and carrier 2 are respectively and

Example 2:

The objects to be transmitted are PUCCH channel 1 that needs to be transmitted on carrier 1 and PUCCH channel 2 that needs to be transmitted on carrier 2, wherein the UCI transmitted on PUCCH channel 1 is hybrid automatic repeat request information, and the UCI transmitted on PUCCH channel 2 is CQI /PMI, since the two channels are both PUCCH channels, the priority can be sorted according to the UCI carried in the two channels respectively. Since the priority of the hybrid automatic repeat request information is higher than that of the CQI/PMI, the PUCCH channel 1 The priority of the PUCCH channel 2 is higher than that of the PUCCH channel 2, that is, the transmission power of the PUCCH on the carrier 2 can be reduced to obtain the available transmission power. Therefore, the available transmission power of the PUCCH channel 2 on the carrier 2 is linearly equal to in, is the linear value of the maximum transmit power, is the linear value of the available transmit power of PUCCH channel 1 (equal to the linear value of the initial transmit power).

Example 3:

The objects to be transmitted are PUSCH channel 1 carrying UCI that needs to be transmitted on carrier 1 and PUSCH channel 2 carrying UCI that needs to be transmitted on carrier 2, wherein the UCI carried by PUSCH channel 1 is hybrid automatic repeat request information and CQI/ PMI, the uplink control information carried by PUSCH channel 2 is CQI/PMI. Since the two channels are both PUSCH, the priority can be sorted according to the UCI carried in the two channels respectively. If the level is higher than CQI/PMI, the priority of PUSCH channel 1 is the priority of PUSCH channel 2, that is, the transmit power of PUSCH on carrier 2 can be reduced to obtain the available transmit power, so that PUSCH channel 2 on carrier 2 The available transmit power is linearly in, is the linear value of the maximum transmit power, is the available transmit power of PUSCH channel 1 (equal to the initial transmit power).

Example 4:

Among the two uplink carriers aggregated by the user equipment, carrier 1 comes from the macro base station, and carrier 2 comes from the micro base station. If the channels to be transmitted by the user equipment in this subframe are two PUSCH channels, the objects to be transmitted are the untransmitted channels that need to be transmitted on the carrier 1. PUSCH channel 1 that carries UCI and PUSCH channel 2 that does not carry UCI that needs to be transmitted on carrier 2, since carrier 1 comes from the macro base station and carrier 2 comes from the micro base station, the priority of PUSCH channel 1 is higher than that of PUSCH channel 2, that is, The transmit power of the PUSCH channel 2 can be reduced to obtain the available transmit power, so that the linear value of the available transmit power of the PUSCH channel 2 corresponding to the micro base station is in, is the linear value of the maximum transmit power, is the available transmit power of PUSCH channel 1 (equal to the linear value of the initial transmit power).

Example 5: The object to be transmitted is PUCCH channel 1 that needs to be transmitted on carrier 1, and PUSCH channel 1 that needs to be transmitted on carrier 2 carrying UCI. The channels can be compared, because the priority of the PUCCH channel is greater than the priority of the PUSCH channel , then the priority of PUCCH channel 1 is higher than that of PUSCH channel 1, that is, the transmit power of PUSCH channel 1 can be reduced to obtain the available transmit power, so the linear value of the available transmit power of PUSCH channel 1 is in, is the linear value of the maximum transmit power, is the available transmit power of PUCCH channel 1 (equal to the initial transmit power).

Example 6: The objects to be transmitted are PUCCH channel 1 that needs to be transmitted on carrier 1, PUSCH channel 1 that does not carry UCI, and PUSCH channel 2 that needs to be transmitted on carrier 2 without UCI. Since the priority of the PUCCH channel is higher than that of the PUSCH The priority of the channel, the power of the PUSCH channel can be reduced. Since there are two PUSCH channels, the two PUSCH channels can be reduced by equal power. Therefore, the available transmit power of the PUSCH channel 1 and the PUSCH channel 2 can be obtained as in, is the linear value of the maximum transmit power, is the available transmit power of PUCCH channel 1 (equal to the initial transmit power).

Example 7: The objects to be transmitted are PUCCH channel 1 that needs to be transmitted on carrier 1 and PUSCH channel 1 that needs to be transmitted on carrier 2 carrying UCI, wherein the UCI carried by PUCCH channel 1 is CQI/PMI, and the UCI carried by PUSCH channel 1 Request information for hybrid automatic retransmission. First, the channels corresponding to the transmission objects can be compared according to the priority ordering of the types of the transmission objects. Since the priority of the PUCCH channel is equal to the priority of the PUSCH channel carrying the UCI, the priority of the UCI carried by the transmission object needs to be further determined. Prioritize the UCI carried by PUCCH channel 1 and the UCI carried by PUSCH channel 1. Since the priority of HARQ information is higher than that of CQI/PMI, the priority of PUCCH channel 1 is lower than that of PUSCH channel 1. level, that is, the transmit power of PUCCH on carrier 1 can be reduced to obtain the available transmit power, so the linear value of the available transmit power of PUSCH channel 1 on carrier 2 is in, is the linear value of the maximum transmit power, is the linear value of the available transmit power of PUSCH channel 1 (equal to the linear value of the initial transmit power).

Example 8:

The objects to be transmitted are PUCCH channel 1 that needs to be transmitted on carrier 1 and PUCCH channel 2 that needs to be transmitted on carrier 2, wherein the UCI transmitted on PUCCH channel 1 is the hybrid automatic repeat request information, and the UCI transmitted on PUCCH channel 2 is also Hybrid automatic repeat request information, wherein carrier 1 is a carrier whose duplex mode is FDD, and carrier 2 is a carrier whose duplex mode is TDD. First, the channels corresponding to the transmission objects can be compared according to the priority ordering of the types of the transmission objects. Since the two channels are both PUCCH channels, it is necessary to further carry out the PUCCH channel 1 according to the priority ordering of the UCI carried by the transmission objects. The UCI and the UCI carried by PUCCH channel 2 are prioritized. Since both channels carry hybrid automatic repeat request information, it is necessary to further prioritize carrier 1 corresponding to PUCCH channel 1 according to the priority of the carrier corresponding to the transmission object. The carrier 2 corresponding to the PUCCH channel 2 is prioritized. Since the duplex mode of the carrier 1 corresponding to the PUCCH channel 1 is FDD, and the duplex mode of the carrier 2 corresponding to the PUCCH channel 2 is TDD, the carrier 2 corresponding to the PUCCH channel 2 The priority of PUCCH channel 1 is higher than that of carrier 1 corresponding to PUCCH channel 1, that is, the priority of PUCCH channel 2 is higher than that of PUCCH channel 1, that is, the transmit power of PUCCH on carrier 1 can be reduced to obtain the available transmit power, thus , the available transmit power of PUCCH channel 1 on carrier 1 is linearly in, is the linear value of the maximum transmit power, is the linear value of the available transmit power of PUCCH channel 2 (equal to the linear value of the initial transmit power).

It should be understood that the above examples are only specific implementations of the embodiments of the present invention, and there are other implementations of the embodiments of the present invention. For example, for example 5, the comparison may not be performed according to the channel type, but the carried UCI may be directly compared, for example, The UCI carried by the PUCCH is the channel quality indicator/precoding matrix indicator, and the UCI carried by the PUSCH channel 1 is the scheduling request. Therefore, the priority of the PUCCH channel 1 is lower than that of the PUSCH channel 1. Therefore, it is necessary to measure the transmit power of the PUCCH. reduce.
